Abstract: Mini scleral lenses in dry eye

Prospective interventional case series, this study included
those patients with grades III and IV dry eye disease, whose symptoms could not
be controlled by conventional treatments. Demographic data, UCVA, BSCVA were
evaluated before fitting. Mini scleral lens fit was assessed by single
experienced practitioner and best corrected vision with mini scleral lens was
assessed. After dispensing mini scleral lens, BCVA with mini scleral lens, and
possible contact lens related problems were assessed in each visit. Ocular
comforts, frequency of artificial tear use, contact lens handling problems were
asked in each follow up visit. For those who did not choose to wear lenses, the
reason was asked. All data were analyzed using descriptive statistical tests.

RESULTS:

Twenty eyes of 13 patients were fitted. Mini scleral lens
was dispensed for 19 eyes in them assessment of fit was either ideal (n=9) or
acceptable (n=10). Seven patients got their lenses; four patients (seven eyes)
of them were satisfied with their lenses based on decrease in discomfort and dry
eye symptoms, decrease artificial tear need frequency and improvement in visual
acuity during mean follow up period of 18.25 months (range: 15-20). None of
them was affected with any contact lens related complication.

CONCLUSION:

Mini scleral contact lenses can be considered helpful in
management of moderate to severe dry eye.
